It's been a tough month. Various things have happened and I've had DS with no overnight contact with his Dad. Me and DP don't live together and haven't been seeing each other as much but try to when we can and call and text etc.
Yesterday one of the school mums suggested going to the pub after school. It's a local village so just a walk from school. There's a child's play park there too. There was 4 school mums in total and DS got to play with his friends and I got some adult company which I don't really get in the evenings or most of the day atm. I had a soft drink as I was driving and it wasn't about going out and getting drunk just socialising really. I was there for a total of 2 hours and DS was having a lovely time. For those 2 hours I didn't look at my phone as was obviously busy. DP had text me a few times with just pics of her and DD at the park. When I hadn't replied for a hour and a half I got hello? So I replied sorry I've been at the pub after school and hadn't a chance to look at my phone. She replied "oh you're one of those parents are you"
I replied and said one of what? One that has a soft drink whilst speaking to friends and my DS enjoying himself with friends. I reminded her what a tough time I've had recently and thought she would be happy that I'm out rather than in alone.
Then she said we'll you took ages to reply. I reminded her that sometimes she can take 2 or 3 hours after school to reply but apparently I'm not thinking of her and ignoring her.
Aibu to be annoyed and refuse to apologise? I feel like I've done nothing wrong
